How To Check Tire Pressure
Inflating and maintaining proper tire pressure ensures safer, more comfortable driving and better fuel efficiency. Particularly in times of high gas prices; in inclement driving conditions such as heavy rain, snow, or ice; and in vehicles of all sizes, tire pressure can make a major difference in driving, wherever you are.
Given the importance of the task, you might think it is complicated, but checking and maintaining your tire pressure is simple, provided you have a good tire air pressure gauge and source of air, both of which are available at many gas stations.
Get a Gauge
A simple tire air pressure gauge, available at most auto parts stores, for a few dollars, is adequate for the job. You do not necessarily need a digital air pressure gauge. If it is worth the $14 to $15 to you, a digital pressure gauge is easy to read and accurate. However, you should consider whether it will require batteries, and whether this would prevent you from using it.
Again, a standard pressure gauge that measures pounds per square inch (PSI) and fits easily in the glove box of your vehicle, is sufficient. Do avoid ultra-cheap models that may not give a proper reading.
As for a source of air, many gas and service stations have air available for 50 cents or so. Some of these air machines have gauges on them, and if you have no other means of measuring the pressure of your tires, these will work. However, they are typically beat and inaccurate, so have your own gauge to ensure the proper PSI for your tires and vehicle.
Checking Pressure
PSI is measured by the notches on a tire air pressure gauge or with a number reading on digital gauges. To find out what PSI is right for your tires, consult your owner's manual or the sticker on the driver's side door. When buying new tires, or getting a rotation, it's a good idea to ask what the ideal pressure is.
